ʻO nā mea hoʻohana plastik maʻamau i loko o nā hale hana
Aia nā mea hoʻohana like ʻole.Ma waho aʻe o nā mea hoʻohana aniani, ʻo ka mea maʻamau i hoʻohana ʻia he mau mea hoʻohana plastic.No laila ʻike ʻoe i nā mea i hana ʻia i nā mea hoʻohana i hoʻohana ʻia i kēlā me kēia lā?He aha nā ʻano?Pehea e koho ai?E pane pakahi aku kakou e like me malalo.
ʻO ka mea nui i hoʻohana ʻia i loko o ke keʻena hanaʻōlelo paipai pipette, nā paipu centrifuge,Nā papa PCR, nā kīʻaha moʻomeheu cell / pā / ʻōmole, cryovial, etc. ʻO ka hapa nui o nā ʻōlelo aʻoaʻo pipette, nā pā PCR, cryovials a me nā mea hoʻohana ʻē aʻe i hoʻohana ʻia he PP.Mea (polypropylene),nā mea hoʻohana moʻomeheu cellhana ʻia me ka PS (polystyrene), hana ʻia nā ipu moʻomeheu cell me PC (polycarbonate) a i ʻole PETG (polyethylene terephthalate copolymer).
1. Polystyrene (PS)
Loaʻa iā ia ka transmittance māmā maikaʻi a ʻaʻohe mea ʻawaʻawa, me ka transmittance māmā o 90%.Loaʻa iā ia ke kūpaʻa kemika maikaʻi i nā hoʻonā wai, akā maikaʻi ʻole ke kūʻē i nā solvents.Loaʻa iā ia kekahi mau kumukūʻai maikaʻi e hoʻohālikelike ʻia me nā plastics ʻē aʻe.Kiʻekiʻe māliko a me ka paʻakikī kiʻekiʻe.
He palupalu nā huahana PS ma ka lumi wela a hiki i ka pohā a haki paha ke hāʻule.ʻO ka mahana hoʻohana mau ma kahi o 60 ° C, a ʻaʻole pono ka mahana hoʻohana kiʻekiʻe ma mua o 80 ° C.ʻAʻole hiki ke sterilized e ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe ma 121 ° C.Hiki iā ʻoe ke koho i ka sterilization electron beam a i ʻole sterilization kemika.
ʻO nā ʻōmole moʻomeheu cell a Shandong Labio, nā kīʻaha moʻomeheu cell, nā pā moʻomeheu cell, a me nā pipette serological i hana ʻia me ka polystyrene (PS).
2. Polypropylene (PP)
Ua like ke ano o ka polypropylene (PP) me ka polyethylene (PE).He resin thermoplastic i hana ʻia mai ka polymerization o propylene.ʻO ka mea maʻamau he paʻa kala ʻole translucent, ʻaʻala ʻole a ʻona ʻole.ʻO kāna pono nui, hiki ke hoʻohana ʻia i nā mahana kiʻekiʻe a me nā kaomi o 121 ° C.E hoʻomaʻemaʻe.
Loaʻa i ka Polypropylene (PP) nā waiwai mechanical maikaʻi a me ke kūpaʻa kemika.Hiki iā ia ke pale i ka ʻino o nā ʻakika, alkalis, wai paʻakai a me nā mea hoʻoheheʻe kūlohelohe ma lalo o 80 ° C.ʻOi aku ka ʻoi aku o ka rigidity, ka ikaika a me ka pale wela ma mua o ka polyethylene (PE).;Ma keʻano o ka pale wela,ʻoi aku ka kiʻekiʻe o PP ma mua o PE.No laila, inā makemake ʻoe i ka hoʻouna māmā a i ʻole ka nānā maʻalahi, a i ʻole ke kūpaʻa kiʻekiʻe a i ʻole nā mea wela wela, hiki iā ʻoe ke koho i nā mea hoʻohana PP.
3. Polycarbonate (PC)
Loaʻa iā ia ka paʻakikī a me ka ʻoʻoleʻa, ʻaʻole maʻalahi ka haki ʻana, a loaʻa i ka wela a me ka pale radiation.Hoʻokō ia i nā koi o ka sterilization kiʻekiʻe-mehana a me ke kaomi kiʻekiʻe a me ka hoʻoheheʻe ʻana i ka ikehu kiʻekiʻe ma ke kahua biomedical.Hiki ke ʻike pinepine ʻia ka polycarbonate (PC) i kekahi mau mea hoʻohana, e like mepahu hauanā ipu erlenmeyer.
4. Polyethylene (PE)
ʻO ke ʻano o ka resin thermoplastic, ʻaʻala ʻole, ʻaʻohe mea ʻawaʻawa, manaʻo e like me ka wax, maikaʻi loa ke kūpaʻa haʻahaʻa haʻahaʻa (hiki i ka haʻahaʻa haʻahaʻa haʻahaʻa ke piʻi i -100 ~ -70 ° C), a palupalu maʻalahi i nā wela kiʻekiʻe.Loaʻa iā ia ke kūpaʻa kemika maikaʻi no ka mea ua hoʻopili ʻia nā molekala polymer ma o nā paʻa kalapona-carbon hoʻokahi a hiki ke pale i ka ʻānai ʻana o ka hapa nui o nā waikawa a me nā alkalis (ʻaʻole kū i ka waika me nā waiwai oxidizing).
I ka hōʻuluʻulu ʻana, ʻo ka polypropylene (PP) a me ka polyethylene (PE) nā ʻano mea maʻamau o nā plastics i loko o nā laboratories.Ke koho ʻana i nā mea hoʻopau, hiki iā ʻoe ke koho i kēia mau mea ʻelua inā ʻaʻohe pono kūikawā.Inā loaʻa nā koi no ka pale wela kiʻekiʻe a me ka wela kiʻekiʻe a me ka sterilization kiʻekiʻe, hiki iā ʻoe ke koho i nā mea hoʻopau i hana ʻia me ka polypropylene (PP);inā loaʻa iā ʻoe nā koi no ka hana haʻahaʻa haʻahaʻa, hiki iā ʻoe ke koho i ka polyethylene (PE);a no nā mea hoʻohana moʻomeheu kelepona ʻO ka hapa nui o lākou i hana ʻia me ka polystyrene (PS).
